| | | | | | | | | | | | inbounds GEPs. This isn't really necessary for simplifying pointer differences, but I'm planning to re-use the same code to simplify pointer comparisons where it is necessary. Since real code almost exclusively uses inbounds GEPs, it doesn't seem worth it to support the extra complexity of turning it on and off. If anyone would like that back, feel free to shout. Note that instcombine will still catch any of these patterns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153418 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach the function cloner (and thus the inliner) to simplify PHINodesChandler Carruth2012-03-25
| | | | | | | | | | | | | | | | | | | | aggressively. There are lots of dire warnings about this being expensive that seem to predate switching to the TrackingVH-based value remapper that is automatically updated on RAUW. This makes it easy to not just prune single-entry PHIs, but to fully simplify PHIs, and to recursively simplify the newly inlined code to propagate PHINode simplifications. This introduces a bit of a thorny problem though. We may end up simplifying a branch condition to a constant when we fold PHINodes, and we would like to nuke any dead blocks resulting from this so that time isn't wasted continually analyzing them, but this isn't easy. Deleting basic blocks *after* they are fully cloned and mapped into the new function currently requires manually updating the value map. The last piece of the simplification-during-inlining puzzle will require either switching to WeakVH mappings or some other piece of refactoring. I've left a FIXME in the testcase about this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153410 91177308-0d34-0410-b5e6-96231b3b80d8

* Move the instruction simplification of callsite arguments in the inlinerChandler Carruth2012-03-25
| | | | | | | | | | | | | | | | | | | | | | | to instead rely on much more generic and powerful instruction simplification in the function cloner (and thus inliner). This teaches the pruning function cloner to use instsimplify rather than just the constant folder to fold values during cloning. This can simplify a large number of things that constant folding alone cannot begin to touch. For example, it will realize that 'or' and 'and' instructions with certain constant operands actually become constants regardless of what their other operand is. It also can thread back through the caller to perform simplifications that are only possible by looking up a few levels. In particular, GEPs and pointer testing tend to fold much more heavily with this change. This should (in some cases) have a positive impact on compile times with optimizations on because the inliner itself will simply avoid cloning a great deal of code. It already attempted to prune proven-dead code, but now it will be use the stronger simplifications to prove more code dead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153403 91177308-0d34-0410-b5e6-96231b3b80d8
